$openssl rand -base64 <number of bytes> - There are 2 concerns here. 1) When we do this (with number of bytes = 24 for T-DES), and use the same as keys, then how do we know that it is a strong key for t-des encryption? 2) Also, in the application, we have to do base64 decode, and the resultant may not be ascii. It can have special characters. I am just wondering if sending this key in any decryption function will cause problems.
